T. rex
• found in marine environments• moves by swimming• eats plankton
• found in African rainforests• also walks on all fours• eats fruits, leaves, and small animalsBonoboBarnacle
• lived 65 to 68 million yrs ago• ate other animals
• found on land• move by walking upright
• made up of many different kinds of cells• each cell has nucleus• move• ingest food found in environment• reproduce sexually

2. Visualization conventions and challengesE.g., Help with zoom E.g., Help with zoom
outsouts
The circle located above and to the right of the microscope illustrates what it would look like if one was looking into the microscope.This image also uses a “zoom-out” convention in that part of the image is at a much higher level of magnification than the rest.

3. Instruction must build upon and address student prior knowledge
E.g., Children confuse genotype & E.g., Children confuse genotype & phenotypephenotype
How come two black labs could have a puppy with a yellow phenotype but two yellow labs could not have a puppy with a black phenotype?
Can a puppy with a black phenotype have a yellow allele as part of its genotype?Why or why not?
